Hello,<br>
<br>
using internal msg flags is one solution for now. Probably you can
push quickly a patch starting from current code, instead of
reverting -- there were few related/similar commits, as I could
spot.<br>
<br>
When I get a chance I will push a function that can tell if a
pointer is in shared memory. Still the flag could be safer to know
if the value has to be freed (pkg/shm) or not at all.<br>
<br>
Cheers,<br>
Daniel<br>

<div>You are correct. Apologies, can you revert that commit and
I will look into it. While this works for not freeing pkg mem
on a shm clone - I see it will break in the other case. I
suspect the only way to do it now is to use msg flags?</div>

the condition to do pkg_free() or not for msg->path_vec.s
doesn't seem correct. You check if path_vec.s points inside
SIP message buffer, but that doesn't happen at all. Path
vector is taken from usrloc record in cloned in pkg for
sip_msg structure.<br>
<br>
Did I misunderstand something?<br>
<br>
Cheers,<br>
